Elwood, played by the charismatic James Stewart, enjoys the company of his invisible friend, which creates confusion and laughter in his surroundings. However, the situation becomes complicated when his sister, Veta, decides that her brother needs professional help to safeguard his image, which has already been somewhat tarnished by the rumors surrounding his unusual companion.

Elwood takes us by the hand through his world, making us question what madness truly is and who are the truly sane. With a heartwarming conclusion, the film leaves us with a bittersweet feeling, reminding us that sometimes happiness can be as fleeting as a rabbit that only we can see.
